Previous studies have reported anomalies of white matter network connectivity in macroscale connectome in reading difficulties. However, evidence of how white matter connections of the reading network associated with phonological deficit in individuals with reading difficulties was rare. The present study aimed to investigate the relationship between white matter topological organization of the reading network and phonological processing skills in 65 Chinese adults (37 good readers and 28 poor readers). Graph-theoretical metrics were employed to capture topological organization features of the reading network. Positive correlations were observed between extrinsic white matter connections from reading network nodes to non-reading-network nodes and phonological processing skills. Specifically, white matter connections between reading network nodes and hubs contributed most to the correlations with phonological awareness. Moreover, correlations appeared to be different in good and poor readers: positive correlations between white matter connections of the reading network and phonological awareness were significant only in good readers, but not in poor readers. Results suggest that the extrinsic white matter connectivity structure of the reading network supports phonological processing ability.

已有研究报道了阅读困难患者宏观连接体白质网络连接异常。然而，关于阅读网络的白质连接如何与有阅读困难的个体的语音缺陷相关的证据很少。本研究旨在探讨65名中国成人阅读网络白质拓扑组织与语音加工技能的关系（37名阅读良好者和28名阅读不良者）。采用图论度量来捕捉阅读网络的拓扑组织特征。阅读网络节点到非阅读网络节点的外在白质连接与语音加工技能呈正相关。具体来说，阅读网络节点和中枢之间的白质连接对语音意识的相关性贡献最大。此外，阅读能力好的读者和阅读能力差的读者之间的相关性有所不同：阅读网络的白质连接和语音意识之间的正相关性仅在阅读能力好的读者中显著，而在阅读能力差的读者中则不显著。结果表明，阅读网络的外在白质连接结构支持语音加工能力。

Word accents are restricted by a word’s morphological structure but also distinguish lexical meanings in minimal pairs. We investigated how early tonal information carried by morphophonemic word accents influences rapid lexical access in native speakers. We also asked whether tone-bearing words are decomposed into morphemes and word accents, or retrieved holistically via full-form neural representations. Here, suffix morpheme and word accent tone were varied orthogonally to create valid and invalid combinations of tone and morphological structure/segmental information. These stimuli were presented in a passive oddball paradigm during an electroencephalography experiment, and mismatch negativity (MMN) responses were obtained.

Valid combinations elicited an early-onset lexical MMN, with main sources in the left middle posterior temporal lobe—an area implicated in lexical memory. Words with morphophonemic tones appear to have full-form lexical memory traces that join segmental and tonal information. As incorrect word accent tones impeded automatic lexical retrieval, we also conclude that word accents may function in a manner similar to lexical tones in distinguishing lexical meanings.

单词重音受单词形态结构的限制，但也能以最小对的形式区分词汇意义。我们研究了语素单词重音所携带的早期音调信息如何影响母语人士的快速词汇获取。我们还询问是否将带有音调的单词分解为语素和单词重音，或者通过完整形式的神经表征进行整体检索。在这里，词尾语素和单词重音的正交变化产生了有效和无效的音调和形态结构/分词信息的组合。这些刺激在脑电图实验中以被动古怪范式呈现，并获得错配负性（MMN）反应。有效的组合诱发了早发性词汇MMN，其主要来源是左后颞叶中部——一个与词汇记忆有关的区域。具有语素音调的单词似乎具有完整形式的词汇记忆痕迹，这些痕迹连接了片段和音调信息。由于不正确的单词重音阻碍了自动词汇检索，我们还得出结论，单词重音可能以类似于词汇音调的方式起着区分词汇意义的作用。

Introduction

The effects of auditory perturbations on reading performance are well studied, but somatosensory perturbations are less understood. Recent research shows oral sensory perturbations (stimulation and anesthesia) improve reading performance in typical readers, though their neural impacts are unclear. This exploratory clinical study investigates how mouth perturbations affect supramarginal gyrus activity during silent reading in a group of typical readers.

Methods

30 English-proficient adults completed orthographic and phonological lexical decision tasks under three conditions: no perturbation, sensory stimulation (lollipop in the mouth), and sensory anesthesia (lidocaine solution swished in the mouth). Functional Near-Infrared Spectroscopy (fNIRS) was used to measure cortical hemodynamic responses of the supramarginal gyrus and the posterior superior temporal gyrus.

Results

Sensory anesthesia reduced supramarginal gyrus activity and facilitated silent reading speed in the phonological task, while accuracy remained unaffected. Sensory stimulation increased supramarginal gyrus activity but did not impact behavioural performance. Neither perturbation affected the activity of the posterior superior temporal gyrus. Both perturbations impacted functional connectivity between somatosensory and auditory cortices.

Conclusion

Taken together, these preliminary and modest effects suggest that oral somatosensory input influence reading-related brain activity and inter-regional connectivity. However, given the preliminary and clinical nature of this study, these findings are interpreted with caution. Ultimately, the importance of somatosensory feedback in reading warrants more targeted exploration to better our understanding of the relationship between speech-motor processes and reading ability.

听觉干扰对阅读表现的影响已经得到了很好的研究，但体感干扰却知之甚少。最近的研究表明，口腔感官干扰（刺激和麻醉）改善了典型读者的阅读表现，尽管它们对神经系统的影响尚不清楚。本探索性临床研究探讨了在一组典型的读者默读期间，嘴部扰动如何影响边缘上回活动。方法30名英语熟练成人在无干扰、感觉刺激（含棒棒糖）和感觉麻醉（含利多卡因溶液）三种条件下完成正字法和语音词汇决策任务。用功能性近红外光谱（fNIRS）测量边缘上回和颞后上回的皮质血流动力学反应。结果感觉麻醉降低了边缘上回的活动，促进了语音任务中无声阅读的速度，但准确性不受影响。感觉刺激增加了边缘上回的活动，但对行为表现没有影响。两种干扰都不影响颞后上回的活动。这两种干扰都影响了体感觉和听觉皮层之间的功能连接。综上所述，这些初步和适度的影响表明，口腔体感输入影响阅读相关的大脑活动和区域间连通性。然而，考虑到这项研究的初步和临床性质，这些发现需要谨慎解释。最终，体感反馈在阅读中的重要性值得更有针对性的探索，以更好地理解语言运动过程和阅读能力之间的关系。

This study investigates neurophysiological, behavioural, and linguistic responses during stressful discourse production. Thirty-six participants completed a Social Stress Test (SST) with five speeches under evaluative feedback conditions ranging from friendly to hostile. Linguistic richness (Lr) was measured via Types-Tokens Ratio (TTR), alongside response times (RTs) and electroencephalographic (EEG) activity (Delta, Theta, Alpha, Beta, and Gamma bands). RTs decreased significantly across tasks, reflecting habituation, while TTR increased under hostile feedback, indicating heightened linguistic adaptability. EEG analyses revealed task-specific neural patterns: Delta power rose during introspective tasks, while Beta activity increased in parieto-occipital regions during hostile feedback, reflecting attentional and visual processing demands. Mindfulness and emotional regulation were associated with better TTR and adaptive neural responses, suggesting resilience against social stress. These findings contribute to understanding the interplay between linguistic, emotional, and neurophysiological processes under social stress and support applications in neurofeedback and mindfulness training to enhance communication under pressure.

本研究探讨应激话语产生过程中的神经生理、行为和语言反应。36名参与者完成了一项社会压力测试（SST），在友好和敌对的评价反馈条件下进行了五次演讲。语言丰富性（Lr）通过类型-标记比（TTR）以及反应时间（RTs）和脑电图（EEG）活动（Delta, Theta, Alpha， Beta和Gamma波段）来测量。在不同的任务中，RTs显著下降，反映了习惯性，而在敌对反馈下，TTR增加，表明语言适应性增强。脑电图分析揭示了特定任务的神经模式：在内省任务中δ能量上升，而在敌对反馈中顶叶-枕叶区域β活动增加，反映了注意力和视觉处理需求。正念和情绪调节与更好的TTR和适应性神经反应有关，表明对社会压力有弹性。这些发现有助于理解社会压力下语言、情感和神经生理过程之间的相互作用，并支持神经反馈和正念训练在压力下加强沟通的应用。

This study compared the neural mechanisms of long-term sensorimotor adaptation in English first language (L1) and second language (L2) speakers using a sustained perturbation paradigm. Behavioral and event-related potential findings demonstrated significant sensorimotor adaptation effects across all experimental phases for L1 speakers but only in the late adaptation phase for L2 speakers, suggesting their efficiency differences in using auditory feedback for the long-term update of feedforward motor commands. This assumption was further supported by source localization results that L1 and L2 speakers recruited similar network for sensorimotor adaptation but L2 speakers activated greater extent. We also identified language-specific changes in theta-gamma phase coherence as speakers adapted to the task, revealing that such coherence may be an indicator of the stability of speech sounds’ sensorimotor representations. Altogether, our findings have implications for understanding how the persistent problem of inaccurate speech relates to L2 speech motor system.

本研究采用持续扰动范式比较了英语第一语言（L1）和第二语言（L2）说话者长期感觉运动适应的神经机制。行为电位和事件电位的研究结果表明，在所有实验阶段，第一语言说话者都有显著的感觉运动适应效应，而第二语言说话者只在后期适应阶段有显著的感觉运动适应效应，这表明他们在使用听觉反馈长期更新前馈运动命令方面存在效率差异。源定位结果进一步支持了这一假设，即母语和第二语言的人在感觉运动适应中招募了相似的网络，但第二语言的人激活程度更大。我们还发现，当说话者适应任务时，theta-gamma相位一致性的语言特异性变化，揭示了这种一致性可能是语音感觉运动表征稳定性的一个指标。总之，我们的研究结果对理解持续存在的言语不准确问题与第二语言言语运动系统的关系具有启示意义。

Semantic control enables context-dependent retrieval of meaning by resolving competition among semantic alternatives. While previous research has implicated left frontal and temporal areas in this process, the dissociation between semantic selection and semantic competition, especially in the domain of written Chinese and across concrete vs. abstract words, remains unclear. Using a parametric modulation fMRI design and a semantic triad task in Mandarin Chinese, we manipulated cue-target and cue-distractor semantic similarity to independently assess selection and competition demands. Activation patterns and functional connectivity were examined across concrete and abstract word conditions. Semantic selection engaged widespread, left-lateralized control and integration networks, while competition primarily activated bilateral superior frontal and insular cortices associated with domain-general conflict monitoring. Word concreteness significantly modulated both processes: concrete word retrieval engaged perceptual and episodic memory systems, whereas abstract word retrieval relied on left inferior frontal and temporal systems. Connectivity analyses showed task- and stimulus-specific modulation of LMFG-RIPL and LMFG-RITG interactions, although these patterns did not survive FDR correction. Semantic selection and competition are functionally dissociable yet dynamically modulated by lexical-semantic features such as concreteness. These findings refine our understanding of the neurocognitive architecture of semantic control.

语义控制通过解决语义选择之间的竞争，使上下文依赖的意义检索成为可能。虽然先前的研究表明左额叶和颞叶区域参与了这一过程，但语义选择和语义竞争之间的分离，特别是在书面汉语领域和具体与抽象词汇之间的分离，仍然不清楚。利用参数调制fMRI设计和汉语语义三联任务，我们操纵线索-目标和线索-分心物的语义相似性来独立评估选择和竞争需求。在具体词和抽象词条件下研究了激活模式和功能连接。语义选择涉及广泛的左侧控制和整合网络，而竞争主要激活与领域一般冲突监测相关的双侧额叶上部和岛叶皮层。词的具体性显著地调节了这两个过程：具体的词检索涉及知觉和情景记忆系统，而抽象的词检索依赖于左额叶下叶和颞叶系统。连通性分析显示LMFG-RIPL和LMFG-RITG相互作用的任务特异性和刺激特异性调节，尽管这些模式无法在FDR校正后存活。语义选择和竞争在功能上是可分离的，但又受到词汇语义特征（如具体性）的动态调节。这些发现完善了我们对语义控制的神经认知结构的理解。

Word reading involves the processing of visual, orthographic, phonological, and semantic information. However, it remains unclear how and when multi-dimensional information is represented in the brain, and the effects of processing demand during reading. To address these questions, the present study used EEG representational similarity analysis (RSA) to explore the time course of multidimensional information representation of Chinese characters and the modulating roles of processing demand. Results showed a hierarchical but dynamically interactive processing mechanism from visual or orthographic information to semantic information in Chinese reading. More interestingly, results showed that Chinese reading greatly relied on the orthographic and semantic processing, but showed relatively weak reliance on phonological processing. Additionally, the explicit task elicited stronger orthographic and semantic representations than implicit task in anterior regions. These results clarified the neural mechanisms of Chinese reading and the modulatory roles of processing demand.

单词阅读包括视觉、正字法、语音和语义信息的处理。然而，目前尚不清楚多维信息是如何以及何时在大脑中呈现的，以及阅读过程中处理需求的影响。为了解决这些问题，本研究采用脑电图表征相似度分析（RSA）来探讨汉字多维信息表征的时间过程和加工需求的调节作用。结果表明，在汉语阅读过程中，从视觉信息或正字法信息到语义信息的加工存在层次分明但动态交互的加工机制。更有趣的是，结果显示汉语阅读对正字法和语义加工的依赖程度较高，而对语音加工的依赖程度相对较低。此外，外显任务诱发的前区正字法表征和语义表征比内隐任务强。这些结果阐明了汉语阅读的神经机制和加工需求的调节作用。

Dysgraphia in Japanese patients with primary progressive aphasia (PPA) remains underexplored. Japanese writing system–kanji (morphograms) and kana (phonograms)–offers a unique opportunity to study dysgraphia in PPA. We investigated 32 Japanese speakers with PPA: 14 with nonfluent/agrammatic (nfvPPA), 13 with semantic (svPPA), and 5 with logopenic (lvPPA) variants. Writing abilities were assessed through the dictation of 30 kanji and 30 kana words. Patients with nfvPPA exhibited significant kana dysgraphia, reflecting phonological route dysfunction. Kanji dysgraphia predominated in svPPA and lvPPA, with phonologically plausible errors most common in svPPA, indicating orthographic-semantic route impairment. Character stroke errors in kana were more frequent in nfvPPA, possibly reflecting graphemic motor deficits. These findings highlight distinct dysgraphia patterns across PPA subtypes, corresponding to the specific brain regions predominantly impaired in each variant.

日本原发性进行性失语（PPA）患者的书写障碍仍未得到充分研究。日文书写系统-汉字（形态）和假名（音）-提供了一个独特的机会来研究PPA中的书写困难症。我们调查了32名有PPA的日语使用者：14名有非流利/语法变体（nfvPPA）， 13名有语义变体（svPPA）， 5名有词性变体（lvPPA）。通过听写30个汉字和30个假名来评估写作能力。nfvPPA患者表现出明显的假名书写障碍，反映了语音通路功能障碍。汉字书写障碍在svPPA和lvPPA中占主导地位，而语音似是而非的错误在svPPA中最常见，表明正字法语义路径障碍。假名的汉字笔划错误在nfvPPA中更常见，可能反映了书写运动缺陷。这些发现突出了PPA亚型中不同的书写障碍模式，对应于每种变体中主要受损的特定大脑区域。

The Cognitive Processing in Bilinguals edited volume (Harris, 1992) included chapters on bilingual long-term memory that made clear that representations of translation-equivalents in bilingual memory overlap. These chapters set the stage for important theoretical and empirical advances that addressed more nuanced questions and provided more definitive evidence, using a broad range of memory paradigms. Research using cross-language memory tests indicate that core conceptual representations for translation equivalents are shared across languages, but language contexts at encoding can serve to facilitate or bias retrieval of language-congruent information. Research on how memory performance varies as a function of language proficiency is generally consistent with explanations based on the relative strengths of word-concept connections. However, connection strength is a more important factor in some paradigms than others and is not the only factor underlying proficiency effects. Limitations of the existing literature and directions for future research are discussed.

《双语者的认知加工》（Harris, 1992）收录了关于双语长期记忆的章节，明确指出双语记忆中翻译对等物的表征是重叠的。这些章节为重要的理论和经验进步奠定了基础，这些进步解决了更细微的问题，并提供了更明确的证据，使用了广泛的记忆范式。使用跨语言记忆测试的研究表明，翻译对等的核心概念表征是跨语言共享的，但编码时的语言语境可能有助于或偏向于语言一致信息的检索。关于记忆表现如何随语言熟练程度的变化而变化的研究，通常与基于词-概念连接相对优势的解释相一致。然而，在某些范式中，连接强度是比其他范式更重要的因素，而不是影响熟练程度效应的唯一因素。讨论了现有文献的局限性和未来的研究方向。

Development of the N400 in infancy 婴儿期N400的发育

In this longitudinal EEG study, we examined the developmental trajectory of the N400 component using a word-picture mismatch-paradigm in 18 infants at 10 and 12 months of age. Event-related potentials (ERPs) were recorded and analyzed in three consecutive time windows (400–600 ms, 600–800 ms, 800–1000 ms post-stimulus). At 10 months, a significant N400-like effect occurred (400–600 ms) but diminished by 12 months, potentially due to developmental changes or increased stimuli familiarity. No significant correlation emerged between N400 amplitude and parental reports of receptive vocabulary. These results imply that the N400 effect is present already in infancy.

在这项纵向脑电图研究中，我们使用单词-图片不匹配范式考察了18名10和12月龄婴儿N400成分的发展轨迹。在刺激后400 ~ 600 ms、600 ~ 800 ms、800 ~ 1000 ms三个连续时间窗记录并分析事件相关电位（ERPs）。在10个月时，出现了显著的n400样效应（400-600 ms），但在12个月时减弱，可能是由于发育变化或刺激熟悉度增加。N400振幅与父母的接受性词汇报告没有显著相关。这些结果表明N400效应在婴儿期就已经存在了。
